I'm using Windows 7 Ultimate 32-bit for over a one year. Now, I was asking if I can run smoothly Windows 7 64-bit. Here's my detail performance, so, can I smoothly and normally run and use 64-bit version? Image: http://www.dodaj.rs/f/32/x8/3CEqb76e/sysreq.png ... One more thing. I tried to install Windows 7 64-bit before, but the installation was too long, display was black too long and system didn't started up for a long time... And, then, I restart PC and install 32-bit again. Regards!
